ADU Builder Midvale, Utah

Midvale’s Go-To ADU Specialists

Ironwood Custom Builders is Midvale’s trusted accessory dwelling unit (ADU) contractor — designing and building garage conversions, basement ADUs, and backyard cottages across the 84047 zip code with the same upfront pricing and detailed planning that defines every Ironwood project. We handle design, permitting, and construction under one roof, so you’re not coordinating between an architect, a contractor, and a permit runner.

Midvale is one of the most ADU-friendly communities in Salt Lake County. The city’s lot sizes, existing garage stock, and proximity to major employment corridors along I-15 and the Cottonwood area create strong rental demand for well-built secondary units. Whether your goal is rental income, space for aging parents, or a home office separate from the main house, Ironwood builds ADUs in Midvale that add permanent, appraised value to your property.

Types of ADUs Ironwood Builds in Midvale

Garage Conversion ADU Converting an attached or detached garage into a fully livable unit is the most common ADU type in Midvale’s 84047 zip code. The existing structure, foundation, and roof are already in place — Ironwood adds insulation, framing, electrical, plumbing, HVAC, and finishes to turn a storage space into a code-compliant, rentable dwelling. Most Midvale garage conversions run between 400 and 600 square feet, producing a self-contained one-bedroom unit with a kitchen and full bath.

Basement ADU Many of Midvale’s post-WWII homes have full-height basements with enough square footage for a complete secondary unit. A basement ADU requires a separate entrance (either an existing walkout or a new stairwell cut), egress windows for any sleeping areas, and independent mechanical connections depending on Midvale’s current code requirements. Ironwood scopes the full project — including any structural work — upfront so there are no surprises mid-construction.

Detached Backyard Cottage (DADU) A new-construction detached ADU built on your existing Midvale lot. This is the most complex and most valuable ADU type — a purpose-built unit designed exactly for its use, with no compromises around an existing structure. Ironwood handles site planning, design, Salt Lake County permitting, and full construction. Detached cottages in Midvale typically range from 400 to 800 square feet depending on lot coverage allowances.

Attached Addition ADU An addition built onto the side or rear of your main home that functions as a separate living unit — its own entrance, kitchen, bathroom, and sleeping area. This works well in Midvale where lot coverage permits expansion but a detached structure isn’t practical.

ADU Permitting in Midvale, Utah

ADUs in Midvale fall under Salt Lake County zoning and building codes. Utah’s ADU-friendly legislation passed in recent years has streamlined the approval process, but permitting still involves zoning review, building permit application, and inspections at multiple stages.

Ironwood manages the entire permitting process for every ADU we build in Midvale:

  • Zoning compliance check for your specific parcel
  • Site plan preparation and submission
  • Building permit application with Salt Lake County
  • All required inspections: framing, rough electrical, rough plumbing, insulation, final
  • Certificate of occupancy

You don’t navigate any of this yourself. Ironwood’s project managers handle it from first submission through final sign-off.

ADU Return on Investment in Midvale

Midvale’s location makes it a strong rental market. Positioned between downtown Salt Lake City and the Cottonwood employment corridor, 84047 draws renters who work in both directions — tech and finance workers heading south, and downtown/University of Utah commuters heading north. A well-finished one-bedroom ADU in Midvale typically commands $1,200–$1,800 per month in rent depending on finish level and parking availability.

At current rates, a garage conversion ADU costing $100,000 to build can generate $15,000–$20,000 in gross annual rental income — a meaningful return on a property you already own. Beyond income, an ADU adds appraised square footage and increases your home’s resale value in a market where secondary units are increasingly valued.

Why Midvale Homeowners Choose Ironwood for ADU Construction

ADU projects carry more complexity than a standard remodel — they involve zoning, structural work, independent mechanical systems, and a longer permitting process. The builders who struggle are the ones who don’t scope everything upfront. Ironwood’s process eliminates that problem:

  • Full project scoping before you commit — we assess your Midvale property, identify every cost driver, and give you a complete number before you sign anything
  • Design-build under one contract — no separate architect, no coordination gap between design and construction
  • Salt Lake County permitting experience — we know what Midvale’s permit office requires and build the timeline around realistic approval windows
  • Single project manager — one person accountable for your ADU from design through occupancy
  • On-time, on-budget guarantee — we don’t hand you surprises mid-project

ADU Builder Midvale FAQ

Most single-family properties in Midvale are eligible for at least one type of ADU under current Salt Lake County and Utah state code. The specifics depend on your parcel’s zoning designation, lot size, and existing coverage. Ironwood performs a zoning compliance check as the first step of every ADU project — we’ll tell you exactly what’s buildable on your property before you spend anything.

A garage conversion typically takes 4–6 months from permit submission to occupancy. A detached backyard cottage runs 8–12 months depending on design complexity and permit review timelines. Ironwood sets a project schedule at the start and keeps you updated throughout — no radio silence during permitting.

Yes. Utah law permits ADU rentals on owner-occupied properties. Short-term rental (Airbnb/VRBO) regulations vary by Salt Lake County zone — Ironwood will identify any restrictions specific to your Midvale parcel during the feasibility assessment.

Not always. Many Midvale ADUs operate on a sub-panel connected to the main home’s electrical service. A separate meter gives tenants independent billing and is required by some lenders for ADU financing, but it adds cost. Ironwood scopes both options in the estimate so you can make an informed decision.
